SCB, June 1992

Estimates of direct investment income and the reinvested earnings component of direct investment capital were shifted to a current-cost (replacement-cost) basis by adjustments to the reported (historical cost) measures of depreciation, depletion, and expensed exploration and development costs. The adjustments were made primarily to ensure that these charges reflected current-period prices, as well as to more closely align income earned in a given period with charges against income in the same period, as required by economic accounting principles. The restatement of income and capital begins with estimates for 1982.
